The C15 reduces CapEx and leverages existing fixed access by connecting to line frames and peripherals of switches such as DMS 10 and DMS 100, as well as MSANs and other IP-based access, enabling operators to effectively discard their TDM switch cores and move customers to the SIP and IMS services cloud.
